A TikTok video is dividing the Internet after a user uploaded an optical illusion, with some seeing a beach and others a car door.

See the illusion for yourself:

The photo that went viral looks like beach scenery with a gloomy dark sky and waves rolling in over the sand.

But that’s not what people we’re actually looking at.

A TikTok user named @HecticNick explained what the real photo is.

As you can see from the image, it’s actually the bottom door of an old, rusty car.

Look again:

Do you see it now? Once you realize it, you won’t unsee it!

Based on the comments, netizens are completely divided with what they saw.

One person just did not have a single clue on what was going on, commenting: “I can see both and my mind is confused.”

Another user’s mind was somewhere else, asking: “Who else thought it was the moon?”

Well, no one else said that they saw a moon.

While a third person must have been looking at something else, commenting: “Am I the only one that saw two snakes?”

The optical illusion was also posted to Twitter and appeared on a Reddit thread, with people all over the internet trying to make sense of what they were seeing.

“Holy s**t I could only see the beach and didn’t know what I was supposed to be looking at,” another person wrote.

“There’s even a ship in the distance, what the f**k?” another one has said.

“It’s a garage door/garage gate,” another person commented.

A person tried to help those who weren’t sure what they saw, explaining: “Don’t know if this will help or if you were kidding, but I’ll try and explain it.”

“The dark blueish sky is the tailgate closed, the water below that is the rear bumper I believe, and it’s silver and there is a chip in the middle, then below that is the ground.”

What do you see? An ocean or the bottom of the car door? Let us know in the comments!
